冷轧窄带钢卷取机 摘 要 冷轧卷取机是轧钢车间中的重要辅助设备，广泛用于冷轧带钢的酸洗、退火、镀锌等生产线上,卷取机的工作状态直接影响着带钢产品的质量，它和生产线出口上的其它设备一起协同工作，将处理后的成品带钢卷成钢卷。近年来，随着用户对钢材的表面量要求越来越高和越来越激烈的市场竞争，卷取机技术逐渐被国内外研究人员所重视。本文首先对卷取机的类型、工艺特点和发展状况等进行了概括性介绍，并对卷取机的结构和工作原理进行了概述；其次，对卷取机的主要部件进行了设计、选择和校核，主要包括：电机的容量选择、减速器的选择；对传动系统进行了设计，主要包括：卷筒轴的设计与校核，轴承的选择和寿命的计算；制定卷取机的总体施工方案，叙述了主要部件的安装、调试的方法和步骤，计算了卷取机的安装工程预算。 关键词 卷取机；设计；校核；施工方案；安装；预算 Cold Rolling Tension coiler Abstract Cold Rolling Tension coiler is the important assistant equipment in cold rolling workshop.The working state of the coiler directly influences the product quality of strip steel. It is widely used in pickling,annealing and galvanization process line.With the cooperation of other equipment in the delivery of line,it will rewind product strip into coil. In recent years,with increasing surface quality by users require on strip and increasingly fierce market competition,coiling technology was gradual attention by the domestic and international researcher. This paper first describe the type of cold-rolled coiler，technological features,development,summary the coiler structure and working principles;Secondly,A major part of the reel of the design,choice and check,mainly including:choice,the choice of gear reducer motor capacity;On the transmission system design,mainly including:the design of the drum shaft and check,the choice of bearing and life ;Arrangements for the overall construction of coiler,describes the main component of the methods and steps of the installation ,commissioning,installation,commissing,installation engineering budget of coiler was calculated. Keywords Coiler;design;check; The overall construction; The installation; budget 目 录 1.绪论 1 1.1选题的背景和目的 1 1.1.1卷取机简介 1 1.1.2卷取机作用 1 1.1.3卷取机背景 2 1.1.4研究卷取机目的 2 1.2冷轧窄带钢卷取机国内外发展状况 3 1.2.1卷取机研究的发展 3 1.2.2冷轧卷取机研究的现状 5 1.3课题的研究方法和内容 6 1.3.1课题研究的内容 6 2.冷轧窄带钢卷取机方案的选择与评述 8 2.1卷取机传动的方案及方案分析 8 2.2主要零部件的选择 9 3.电动机的选择 11 3.1带钢张力的计算及最大张力的确定 11 3.2卷取机主要结构尺寸的选择 12 3.2.1卷筒直径的确定 12 3.2.2卷筒筒身长度的
